Daily brief

Configuration

Look for a brief.json in the working directory (or ask the user once and create it):

{
  "title": "Morning brief",
  "feeds": ["https://hnrss.org/frontpage", "https://blog.ethereum.org/feed.xml"],
  "pages": ["https://www.x402.org/"],
  "coins": ["bitcoin", "ethereum", "tron", "binancecoin"],
  "since_hours": 24,
  "max_items": 12,
  "language": "en"
}

Steps

1. Fetch feeds: download each feed, parse <item> / <entry>, keep items newer than since_hours. Record title, link, published time, source.
2. Fetch pages: for each page, compare with the copy saved in .brief-cache/ from the last run; include only meaningful changes (ignore dates, counters, ads).
3. Market data: GET https://api.coingecko.com/api/v3/simple/price?ids=<coins>&vs_currencies=usd&include_24hr_change=true. Report price and 24h change; do not predict prices.
4. De-duplicate: merge items about the same story (same link or near-identical titles) and keep the most authoritative source.
5. Rank and group: by topic (e.g. AI, Crypto, Product updates), most important first, up to max_items.
6. Write in language:

# Morning brief — 2026-10-04

## Market
| Asset | Price | 24h |
|---|---|---|
| BTC | $… | +1.2% |

## AI
- **Headline** — one-sentence summary. [Source](link)

## Crypto
- …

7. Save the fetched pages to .brief-cache/ for the next run's diff.

Rules

Every bullet must link to its source. Summaries must reflect the source, not add opinions. If a source fails to load, list it under "Unavailable sources" instead of silently dropping it.
